Biomolecules
Used for fast energy
What is a carbohydrate?
This type of protein facilitates the start of reactions by lowering the activation energy.
What is an enzyme?
This process occurs in the nucleus and is used to copy the DNA into an mRNA strand.
What is transcription?
This is the part of the cell cycle where more DNA is produced.
What is s-phase?
During this phase the chromosomes are aligned on the equator of the cell
What is metaphase?
This molecule can be a channel, pump, enzyme or antibody
What is a protein?
This protein is used during active transport of molecules against their concentration gradient.
What is a protein pump?
This molecule is used during translation to carry amino acids to the ribosomes.
What is tRNA?
This part of the cell cycle is divided in more sub-phases and can produce either gametes or somatic cells.
What is M-phase?
During this phase the chromosomes are beginning to form and the DNA is in the process of changing from chromatin to chromosomes
What is prophase?
This molecule can be found mainly in the cell membrane. It is also used for long-term storage of energy and insulation
What is a lipid?
This protein is used to allow the diffusion of molecules across the cell membrane following their concentration graditent.
What is a channel protein?
This molecule is a single long sequence of amino acids.
What is a polypeptide?
Towards the end of this part of the cell cycle the cell may get the information to produce more cells.
What is G1 phase?
During this phase the chromatids are pulled to opposite poles of the cell
What is anaphase?
Determines function of all molecules
What is structure?
This protein is used by cells to recognize each other and communicate. It is found on the cell membrane
What is a receptor protein?
This is the section of DNA that codes for a polypeptide.
What is a gene?
This happens whenever mutations in the cyclins coding genes occur and the cell cycle never stops
What is cancer?
During this phase two nuclei are being formed.
What is telophase?
These molecules can be found in a nucleus, in the cytoplasm, or even wrapped in protein coats (in the case of a virus).
This process is used to make a sequence of nucleotides from an mRNA.
What is translation?
This is the version of the gene that is transcribed and translated more than the other versions and, therefore, is expressed more and shown more.
What is a dominant allele?
This is the phase when the cell just does what the cell needs to do and exits the cell cycle
What is G0
This short phase follows mitosis and ends the cell cycle by producing two distinct cells.
What is cytokinesis?
